This study was carried out to compare agro-morphological traits and nutritive value of 25 tall fescue (Festuca arundinacea) ecotypes grown in Tehran, Iran. The experiments were carried out in a split plot design during 2016-2018 growing seasons. The results showed that there was a significant genetic variation in existing germplasm. The highest heritability was related to dry forage yi...
to evaluate the effects of pgpr foliar spraying on forage and grain yield of forage sorghum (var. speedfeed), a farm experiment was conducted in research farm of college of agriculture, university of tehran in 2009. the experimental design consisted of a randomized complete blocks consisting of 17 treatments in every block. in this research, the effect of foliar application of 16 different stra...
To evaluate the effect of seed pre-soaking on forage yield and quality and water productivity in late planting of two forage sorghum cultivars, a field experiment was conducted was conducted as split factorial arrangements in randomized complete block design with three replications in 2017 and 2018 growing seasons at the research field of Seed and Plant Improvement Institute, Karaj, Iran. Four ...
This study was conducted to investigate the genetic diversity of alfalfa genotypes by multivariate analyses using agronomic and morphological traits. For this purpose, 20 alfalfa genotypes with local control Baghdadi was considered as the first factor and three harvest was used as the second factor. This experiment was performed to split plot at the time in randomized complete block design with...
In order to evaluate the effect of row and plant spacings on the yield and yield components of three cultivars of forge sorghum, a field experiment was conducted in Isfahan University of Technology, Lavark, during spring, 2001. Experimental design was a split-factorial with three replications. Main plots consisted of three row spacings (45, 60, 75 cm) and subplots were combinations of three cul...
in order to investigate of different salinity stress and plant densities effects on quantitative and qualitative forage and grain yields of kochia a randomized complete block design in factorial arrangement with three replications was used. a field study was conducted in 2011 cropping season in agriculture experiment satiation, college of agriculture, islamic azad university, arak branch treatm...
تأثیر آبیاری تکمیلی و تیمار پیش جوانهزنی بذر بر صفات کیفی، عملکرد علوفه تر و خشک ماشک رقم دیم مراغه
To evaluate the effect of supplemental irrigation and seed priming on yield and some quantity and quality characteristics of vetch (Vicia dasycarpa) rainfed maragheh cultivar, an experiment was carried out at the Research Farm of Faculty of Agriculture, University of Urmia, West Azarbaijan province, Iran, during 2011. The experiment was laid out using split-plot, based on Randomized Complete Bl...
field trials. The use of row-column analysis or neighbor analysis has been shown to increase the precision of a Spatial analyses of yield trials are a powerful method of adjusting large number of grain yield trials (Cullis and Gleeson, treatment means for spatial variation and improving statistical precision of mean estimation. Because yield trials are typically repeated 1989; Cullis and Gleeso...
Combining ability in forage sorghum [Sorghum bicolor (L.) Moench] was not as much investigated as in grain sorghum. In the present study, 4 local stocks (Testers) and 7 exotic stocks in A3 cytoplasm were crossed in line x tester fashion to investigate combining ability in forage sorghum. The hybrids and their parents were evaluated across two years (2002 2003) and at two locations in Khartoum S...
In order to evaluate the effect of water stress and nitrogen levels on yield and some agronomic traits of two forage sorghum cultivars, a field experiment was conducted at the Faculty of Agriculture, Shiraz University, during Spring and Summer 2011. The experiment carried out as split-split plot based on randomized complete block design, with 3 replications. Water stress levels of 100, 75 and 5...
